Update:
FC held to 9 overnight (no CC) and water is clearer yet.pH is 7.3 before sunrise this morning so I am now dosing Alk to get it stable, currently at 50ppm. Added 2lbs of BS, should need another 6lbs or so to get to 100.
Question: Why did the pH drop? there has been no rain and I am using 12.5 liquid bleach.
